From there, choose Disk Utility. Instead, youвЂ™ll see the macOS Utilities window. While in Recovery mode, you wonвЂ™t see your usual login screen. How to restore a Mac to factory settings with Recovery mode.

Follow these guidelines during installation: If the installer asks to unlock your disk, enter the password you use to log in to your Mac. Select Reinstall macOS from the utilities window in macOS Recovery, then click Continue and follow the onscreen instructions. ItвЂ™s clean because it isnвЂ™t simply installed on top of your existing files, and itвЂ™s a re-install because those system files are there already.Professional use of Docker Desktop in large organizations (more than 250 employees or more than 10 million in revenue) requires users to have a paid Docker.Reinstall macOS. When you need to go back to square one and return to a вЂcleanвЂ™ installation of macOS, simply re-installing macOS is insufficient: what you need is a clean re-install.

This is what I see in Terminal when it opens.In Mojave and earlier, a clean re-install is straightforward if time-consuming. MacBook Air: Mac OSX Sierra 10.12.3. I've tried to research this, and performing commands such as 'bash exit' seem not to work. I'm using MacBook Air 2014 and tried to install a Python library via command line in terminal.

Because you want to re-install macOS, the logical thing to do would be to wipe the System volume, which suggests that you could get away with retaining your own files on the Data volume through a clean re-install. The first of those is the read-only System volume, and the second the read-write Data volume. What determines the source and version of macOS to be re-installed are the keys you hold down to enter the mode in the first place.Try this in Catalina and the first thing youвЂ™ll realise is that you donвЂ™t just have a single boot volume now, youвЂ™ve got two, one called something like Macintosh HD, the other Macintosh HD - Data.

However, as of 10.15.2 that doesnвЂ™t work, and results in the creation of yet another Data volume named Macintosh HD вЂ“ Data вЂ“ Data.Deleting the Data volume does make a difference to the end result: when you delete the Data volume then add it back, its Unix-style volume number has changed, perhaps from 2 to 1, and that of the System volume goes from 1 to 5. If that happens, restart into Recovery mode and repeat the process of erasing the System volume, which should succeed on the second try.If youвЂ™re performing this clean re-install to try to fix a problem, and donвЂ™t want to make its current data particularly inaccessible, then all you should need to do is select the Data volume and erase it when you re-install macOS that should overwrite everything on the System volume, which is, after all, read-only in normal use. This is described by Apple in this detailed support note, but commonly fails with an error reporting that вЂThe volume вЂњMacintosh HDвЂќ on disk2s5 couldnвЂ™t be unmounted because it is in use by the process 734 (kextcache)вЂ™.

If you try to install macOS onto the original System volume, Macintosh HD, youвЂ™ll discover thatвЂ™s not possible, so select the Data volume here, Macintosh HD - Data instead.The commonest and most peculiar problems arise when the installer gets overenthusiastic about creating new Data volumes, and you end up with additional volumes with names like Macintosh HD - Data - Data. Whichever type of re-installation you have set now requires that version of macOS to be downloaded afresh.Depending on which version of Catalina itвЂ™s running and how you erased volumes using Disk Utility, you may be presented with a choice of volumes on which to install macOS, which could be a surprise. At one time, the Recovery volume contained sufficient to restore the current version of macOS if you have entered вЂlocalвЂ™ Recovery Mode using Command-R, but this doesnвЂ™t seem to work any more.

This is then the squeakiest clean of clean re-installs, but should very seldom be necessary.Thanks to Vladislav for information about the difference between volume numbering according to the procedure used.Updated 21 December 2019 with corrections from field testing.Thank you. The reason that this is now unpopular is that, if your Mac has a T2 chip, you canвЂ™t boot it from an external disk without entering Recovery Mode first to enable that, rather then running in the default Secure Boot mode.Once booted from that external disk, you can then use Disk Utility to erase the whole internal storage back to a GUID Partition Map, then run the macOS installer of your choice to install macOS onto it, during which it will create the various volumes it requires. Exiting the install process at the start of its customisation steps doesnвЂ™t leave your Mac in a position to be able to mount as a Target Disk, for example.To take your internal storage right back to the beginning and set it up from scratch, you should be able to do this when booted into either of the вЂremoteвЂ™ Recovery Modes, but itвЂ™s most reliably done when booted from an external disk. This may seem a pain, but itвЂ™s worth getting your volumes straight before going any further, or youвЂ™ll only store up problems for the future.Unfortunately, once you have started your clean re-install, thereвЂ™s no way to check that everything is going OK until macOS has been fully configured. Delete all the Data volumes and erase (not delete) the System volume, then re-install.

Therefore, it is up to the user to decide whether they want to erase either or both of the volumes in the Volume Group, or want to delete them altogether.The installer then has the task of examining the bootable APFS container and ensuring that it has the correct volume structure, including the Recovery volume, as well as both System and Data volumes. The вЂcleanвЂ™ part is preparation performed by the user, not any different behaviour on the part of the installer. It doesnвЂ™t, as far as I can see, break the old Volume Group, nor start creating new volumes, either System or Data, nor should it.A clean re-install should behave exactly the same, and respect any System and Data volumes where they already exist.

Exchange your MacвЂ™s HD with an SSD. For help doing that, you need to do some googling.2. You could go back to using High Sierra, but youвЂ™d first have to back everything up and then reformat the startup disk in HFS (Mac OS Extended journaled) format, and then re-install High Sierra on it. If even opening a folder in Finder has become noticably slower, thatвЂ™s very likely the reason for it.1. If you are still using hard disks instead of SSDs, then APFS has made them slower, by at least a factor of 2.

This carried a little problem with it from the old computer, so I thought IвЂ™d clean re-install Catalina and then use the TimeMachine backup instead, and as soon as I got the adapters USB-A to USB-C I did itвЂ¦ And now I have the dreadful вЂњMacintosh HD вЂ“ Data вЂ“ DataвЂќ thing.AND, as I didnвЂ™t notice it right away, I also had the computer perform a few TimeMachine backups since, so I believe I shouldnвЂ™t use it anymoreвЂ¦вЂ¦So I airdropped all the new files I created in the meanwhile to the old computer, and want to clean install again and solve this вЂњdata-dataвЂќ problem. рџ¦I bought a MacBook Pro 16 and made the вЂњmigrationвЂќ from my old MacBook Pro importing straight from the computer. IвЂ™m Italian, and IвЂ™m trying to follow your instructions, but I found a bit of a problem. There are also people who do this for you, look for local services.Thank you a lot for this post.
